Two supported strengths
Growth 80/100 and Stability 63/100.
Weakest measured signal
Cash Flow is the weakest category at 34/100.
Primary evidenced risk: price-to-income affordability is the weakest measured factor (19th national percentile). Data caveat: price is Zillow Bottom-Tier ZHVI (5th–35th percentile); rent is ZORI asking rent and is not bedroom- or property-matched. Insurance is a 0.5% annual allowance, not a quote.
Scenario buy-hold-v1-2026-09-19: 7% fixed financing for 30 years; 20% and 25% down; 5% vacancy; 8% management on collected rent; 5% maintenance and 5% CapEx on scheduled rent; measured local property tax; 3% closing costs. Qualification also requires positive cash flow, Hold Coverage at least 1.10, nonnegative cash flow after 10% lower rent, and the existing quality and data gates.
Property verification checklist
- Confirm achievable rent with bedroom-matched comps, current listings, and any existing lease.
- Use the parcel’s actual tax bill and reassessment rules.
- Obtain a landlord insurance quote, including wind, flood, or named-storm coverage where relevant.
- Inspect roof, structure, mechanicals, deferred maintenance, and immediate capital needs.
- Verify utilities, HOA, licensing, inspection, registration, and local rental rules.
- Replace the modeled loan with a current lender quote, points, closing costs, and reserve requirements.
Why this grade
Overall 55.3 is a weighted geometric mean of the three category scores. Because they are multiplied rather than averaged, their distances from a perfect 100 combine as an exact identity, and each category's share of that distance is the arithmetic below, not an estimate. Cash Flow carries 63% of it, which is what makes it the binding constraint on this grade.
Inside Cash Flow, the shortfall splits over the factors the model scored here, exactly, in proportion to their published weights. The largest component is expense-adjusted yield (weight 22 of the category's 35, 43rd national percentile, 54% of the category's own shortfall); next is price to income (weight 13 of the category's 35, 19th national percentile, 46% of the category's own shortfall).
What this is not. It is not a claim that a different value on any one factor would produce a different score or a different grade. Every factor is scored as a national percentile and the grade is a percentile cut against the other 4,812 ranked markets, so this market's position moves only relative to all of them, never on its own. All 13 factors were measured for this market, so no category is carrying a gap.
How Boise City ranks nationally
Each row places Boise City against all 4,812 ranked U.S. markets. The marker is this city; the centre tick is the national median, and the bar spans from that median to the marker, so its length is how far from the middle of the country this market sits and the side it falls on is the direction. Further right is more favorable to an investor: inverted measures (crime, vacancy, price-to-income) are already flipped so higher always means better here.
What a deal looks like here
A market-level buy-box for Boise City, built from this market's own numbers: the investor-entry price, its rent, and local carrying costs. The market grade is a quality screen; the deal verdict below is this financing scenario only. An illustrative scenario, not a listing.
Does not meet screen. At 25% down, named scenarios span −$1,040 to −$890/mo after reserves (10% lower-rent stress to base case). This range is not a confidence interval.
Buy target = Zillow Bottom-Tier ZHVI (5th–35th percentile) $398,565; typical home value $503,852. Rent = Zillow ZORI typical asking rent. Assumptions: 25% down, 7% / 30-yr, 5% vacancy, 8% management on collected rent, 5% maintenance, 5% CapEx reserve excluded from NOI and subtracted from cash flow, 0.5% insurance, 0.59% property tax. Illustrative market-level scenario: not a listing, appraisal, recommendation, or underwriting decision. As of 2026-07-10.
Market Negotiation Leverage
Strong seller leverage (14th percentile among 6,196 cities with Redfin coverage)
Equal-weight composite of three Redfin signals’ national percentiles (days on market 11, months of supply 1.0, sale-to-list 100.4%), direction-adjusted so a higher percentile always means more room for a buyer to negotiate. This is a cross-sectional snapshot against every other tracked city today, not a seasonal or historical baseline for this specific city (no multi-year time series is committed for this data). Not a prediction of what any specific seller will accept. Source: Redfin Data Center. See how this is calculated.
Measured market data
Measured observations for Boise City, shown as context beside the market score (none of it feeds the score), and the model weights are unchanged. These are different measurements from the Census figures in the factor table: the ACS median value is what owners report in a 5-year survey, while ZHVI is a monthly index of typical value; ACS median gross rent is what sitting tenants pay including utilities, while ZORI indexes asking rent on newly listed units. Neither corrects the other. Monthly series, revised in recent months, observed 2026-07, not live.

ZIP markets in Boise City
14 Census ZIP Codes (ZCTAs) officially overlap Boise City by land area · 12 data-eligible for subscores. Overlap is Census land-area share, not a population or address share. Each ZIP Code's overall Rental Investor ZIP Score, grade and canonical national rank are shown below (the two component signals, affordability and rental market, are separate percentiles). There is no city-scoped ZIP rank: city overlap isn't a ranking universe, so only the national rank is shown. These ZIP rankings sit in the ZIP universe only, never mixed with, and not directly comparable to, Boise City's city ranking. Vintage: the Key metric column below is Census ACS 2020–2024 (5-year), the same survey release as the figures used above for Boise City itself; a city and a ZIP Code are different geographies, so the same measure can still show a different number at each level.

The honest read
Boise City scores 55/100 overall (grade B): 34 for Cash Flow, 80 for Growth, and 63 for Stability, each a 0–100 score built from the factors in that category. The scenario above shows what a representative investor-entry purchase pencils out to at today's rates. Everything we can measure is in the table below, with its source.
Every factor, shown
The Overall score blends three category scores built from thirteen measured factors: Cash Flow (35%), Growth (35%), and Stability (30%). The table shows every factor; the tag on each percentile marks which category a scored factor feeds. Untagged factors are shown for context but not scored. Every percentile also carries the band it falls in - top 10%, top quartile, above or below the national median, bottom quartile, bottom 10% - so a bare ordinal still reads as a position; the band restates that percentile and adds nothing to it. Every value carries its source and as-of date. How the score works.
| Factor | Value | National percentile | Source · as-of | What it means |
|---|---|---|---|---|
| Expense-adjusted yield | 2.5% | Below median43rd percentile · Cash Flow | Zillow ZORI/ZHVI · 2026-08-31 | Annual rent divided by price, net of a modeled vacancy, tax, capex, and management allowance: the core of the Cash Flow category and what the score is actually computed from.
